Features
- Harman’s patented Plus One cones provide more overall speaker cone area (up to 35%) than other cones in its class
- Infinity Primus speakers are engineered with edge-driven silk dome tweeters which expand the high-frequency range and ensure you'll hear all the natural detail of your favorite tunes.
- Infinity Primus speakers feature a compact design for easy installation in tight spaces, allowing them to fit into more vehicles without the need for modifications and cutting.
- The super-rigid vented baskets help to cool the voice coils making for a reliable speaker. They provide a real world benefit by wicking heat way from the motor structure almost like a fan as the cone moves through its stroke.
- Infinity Primus speakers are carefully tuned to ensure each line has the consistent Infinity sound signature.
